CARL KRUSE AND ERNST J. KRUSE, OF SEATTLE, WASHINGTON.

BREAD KNEADING AND MOLDING MACHINE.

Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed June 19, 1906. Serial No. 322,485.

To aZZ whom it may concern:

Be it known that we, CARL KRUSE and EnNsT J. KRUsE, citizens of theUnited States, residing at Seattle, in the county of King and State ofWashington, have invented certain new and useful Improvements in BreadKneading and Molding Machines, of which the following is aspecification.

The object of our invention is to provide an improved construction ofbread kneading and molding machine which will be composed ofcomparatively few and simple parts, which will be durable, and whichwill be efficient in operation to thoroughly knead the dough and retainthe gases of fermentation therein in a finely-distributed manner andwhich will at the same time it is kneading the dough form it into aloaf, the parts being so arranged that loaves of different sizes may beformed by certain adjustments of the parts.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings, in which Figure 1 is a perspective view. Fig.2 is a transverse sectional view. Fig. 3 is a vertical longitudinalsection. Fig. 4 is a detail view of the kneadingboard.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, the numeral 1 designates the side bars of theframework or casing of our improved bread kneading and molding machine.Upon the upper edges of these side bars pillow-blocks 2 are mounted, andcrank-shafts 3 are journaled in said pillow-blocks and extend inparallel relation transversely of the machine. Each crankshaft isprovided with a pulley 4 at one end,

and said two pulleys are connected together by means of a belt 5, sothat both shafts may work together. The shafts may be operated in anysuitable manner, as by a handle 6, se cured to the outer end of one ofthem.

A kneading and molding board 7, extending longitudinally of theframework or casing and fitting substantially the side bars 1, isprovided with an upwardly-extending supporting-rib S, journaled upon thecranks of the shafts 3. Hence as the crank-shafts 3 are rotated it isevident that the kneading and molding board 7 will have imparted to it asubstantially circular vibratory motion. The lower face of the board 7is provided with a series of transversely-extending corruga- 6o tions 9.

The bottom 10 of the machine is consti-' tuted by a board supported inthe side bars 1 in a vertically-adjustable manner, as by set screws orthe like. It is located underneath the board 7. An endless apron 11 ismounted to travel over the upper face of the bottom board 10 uponrollers 12-, which are mounted in bearings 13 in the side bars. Theshaft of 'one of these rollers 12 is extended at one end,

and upon the shaft extension is mounted a relatively larger pulley 1 1,which is connected with a smaller pulley 15 on one of the crank-shaftsby means of a belt 16. .By this means as the kneading and molding board7 is vibrated a traveling motion will be imparted to the apron 11. Thismotion, which is concurrent with the motion of the kneading and moldingboard, may be changed from one direction to the other, as required, by

changing the driving-belt 16 from an untwisted to a twisted position, orvice versa.

17 designates a feed-plate freely supported at one end by a spindle 18,extending transversely of the casing or framework of the 8 5 machine atone end of the latter. The feedplate is adapted to be supported directlyupon the apron 11 and indirectly by the bottom board 10, so that itsinclinations may be varied according to the different elevations of thebottom 10, and it is to be noted that this inclined feed-plate, which isprimarily intended to feed the dough into proper position for actionthereupon by the corrugated board 7, will also act as a scraper for the5 apron and tend to keep the same sufficiently clean for its properoperation.

In practical use the dough to be kneaded and molded into loaves is feddown the inclined feed-plate 17 while the shafts 3 are being rotated bymeans of the handle 6 or similar actuating means. As the dough is caughtbetween the members 7 and 10 it will be properly kneaded and at the sametime will be carried forwardly toward the op- 10 5 posite end of themachine by the apron 11, which, as noted, travels in a horizontal planeunderneath and 1n proper relation to the board 7. As the dough comesfrom the machine it is discharged in the form of loaves. 1 1o The sizesof these loaves, so far as their diameter is concerned, may be varied byvertically adjusting the bottom board 10.

Having thus described the invention, what is claimed as new is 1. Adough kneading and molding machine, comprising a framework embodyingvertical side bars, crank shafts journaled on said side bars andconnected together for simultaneous operation, a kneading and moldingboard mounted between said side bars and provided with anupwardly-extending rib j ournaled on the cranks of said shafts, thelower face of said board being formed with transverse corrugations, abottom board underneath the first-named board, an apron designed totravel on said bottom board, an operative connection between thecrank-shafts and said apron whereby they may be simultaneously actuated,and a freelyswinging feed-plate supported by said board and apron at oneend of the machine, the free edge of said feed-plate resting upon theapron and thereby serving as a scraper therefor, in addition to feedingthe dough into proper position for action thereupon by the mountedbetween the side bars above the bottom board, crank-shafts journaled onsaid side bars and operatively supporting said corrugated board, anapron mounted to travel over said bottom board and an operativeconnection between one of said crankshafts and said apron.

In testimony whereof we affix our signatures in presence of twowitnesses.
